Holding Module Linkage Mechanism for Circuit Board Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing installation process for circuit boards in holding modules is complex, costly, and prone to damage due to the need for precise alignment and the use of multiple screws, which can lead to user errors and connector damage.
Innovation Solution
A holding module design featuring a fixation member with a linkage mechanism that allows for easy vertical installation and removal of circuit boards without additional tools, using a pivotally connected linkage member to guide the board into place and secure it within the holding member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fixation rack with multiple screws is used to secure the circuit board, then the holding member maintains structural robustness, but the installation process becomes complicated and time-consuming
Solution Approach 1:
The fixation rack is divided into multiple independent fixing components (first fixing component and second fixing component) that can be independently operated. Each fixing component has its own fixing hole and screw, allowing sequential installation rather than requiring all screws to be installed simultaneously through complex alignment procedures.
Solution Approach 2:
The circuit board is pre-positioned in the holding member before the fixation rack is installed. The first fixing component is installed first to secure the board in a preliminary state, then the second fixing component is added to complete the fixation. This preliminary positioning eliminates the need for complex alignment during the final installation step.
2Ease of manufacture
If the circuit board is installed inclinedly to accommodate the fixation rack, then the fixation rack can be installed, but the alignment between connectors and connection holes becomes difficult and may cause damage
Solution Approach 1:
Instead of tilting the holding member or circuit board to accommodate the fixation rack installation, the invention inverts the approach by designing the fixation rack to be installed in the same horizontal plane as the circuit board. The first and second fixing components are positioned such that their fixing holes align with the circuit board without requiring any angular adjustment, thereby eliminating connector misalignment risks.
3Reliability
If nine screws are used to lock the circuit board and three additional screws to fix the fixation rack, then secure fixation is achieved, but the installation cost and time increase
Solution Approach 1:
The invention merges the circuit board fixation and fixation rack installation into a unified process. The first fixing component serves dual purposes: it secures the circuit board to the holding member and simultaneously provides the structural basis for installing the second fixing component. This integration reduces the total number of screws from twelve to two and eliminates sequential installation steps.

AI summary
A holding module is installed in a chassis of an electronic device. The holding module is used to hold an expansion module and includes a holding member, a fixation member, and a linkage member. The holding member includes a carrier plate, a first side plate, and a second side plate. The first side plate and the second side plate are connected to two opposite sides of the carrier plate, respectively. The fixation member is pivotally connected to the first side plate and the second side plate. The fixation member is provided with a linkage portion. The linkage member is rotatably arranged in the holding member. The linkage member includes a docking portion and a pushing portion. The docking portion is connected to the linkage portion. The pushing portion is connected to the expansion module selectively.
